NEW YORK – The Centers for Medicare and Medicaid Services and the US Departments of Labor and the Treasury on Saturday issued guidance requiring private health insurance to cover, at no cost, diagnostic testing for SARS-CoV-2, the coronavirus that causes COVID-19.

The guidance covers molecular-based testing, as well as serology tests.

Under the guidance, group health plans and group and individual health insurers must cover diagnostic testing and "certain related items and services" during a medical visit without any cost sharing.
